That sure looks like the part. Your research skills are impressive! I wasn't even thinking about it, now I feel like I need one. It does seem crazy not to have the speakers better protected.Hi Wojtas. I realize you and some other members are located overseas and may not/do not have access to a Lincoln Dealership (but maybe have access to a Ford Dealership?). Heck, some in the US do not even have easy access to a Lincoln Dealer.
That is why I did not quote you, since my reply was not directed to those with no Lincoln (or Ford) Dealer access. However, there were also others here asking where/how to get that trunk trim piece who do have access to a Lincoln or Ford Dealer.
So on the same subject, I took the time to look up the part number on an online Ford parts distributor, and if I have the correct part, it seems to be listed in the "Interior Trim > Rear Body" section as the...
Upper Cover - Ford (FP5Z-5445443-CA)
I believe that is the trim piece, and not the sheet metal package tray/shelf itself, It certainly seems to be, from the description..."Carpet Rear Package Tray Pan".
But it is a bit difficult to precisely determine from the exploded diagram. However, a quick call to a Lincoln or Ford Dealer can settle that question, for those with access to one or the other.
If you have access to a Ford Dealer in Poland, you can check to see if the Mondeo uses that part on their upper trim level vehicles. It would not surprise me if they do.
Keep us updated and good luck.
